PROJECTILE.

Patented Oct. 31, 1905.

Application filed June 27, 1904:. Serial No. 21,825.

To all whom it may concern:

Be it known that I, JoHN W. ANDERSON, a citizen of the UnitedStates,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in Projectiles, of which improvement the following is aspecification.

The invention described herein relates to certain improvements in armorpiercing projectiles, and has for its object a construction whereby theprojectile will be caused to be tipped or turned immediately prior toimpact of its body with the surfaces of the armor or protective deck andwill thereby' be so tilted or changed in its line of movement as tochange the angle of its axis to the surface of the armor or deck. As nowconstructed armor-piercing projectiles whose points are made exceedinglyhard and conical will when they strike upon an inclined surface and thecurved rotected deck of the war vessel be deflected unless the angleformed by the axis of the projectile and the surface of the armor at theinstant of impact are greater than half the angle formed by the sides ofthe projectile. In order to prevent or lessen this glancing of theprojectiles, I provide suitable readily-frangible means which willstrike the armor or deck slightly ahead of the project ile, and so tipor turn the projectile that the angle of its axis with the plate will beincreased.

The invention is hereinafter more fully de scribed and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation of' the projectile having my improvementapplied thereto; and Fig. 2 is a view similar to Fig. 1, illustrating amodification of my improvement.

In the practice of my invention the projectile 1 is of the usual form ofconstruction, having the conical piercing-point. Such projectiles unlessthe point of impact on the projectile coincides approximately with itsapex will be deflected without producing any material injury to theplate. In order to insure or increase the penetration of the curveddeck-plates, even when the direction of movement of the projectile priorto im act is at an angle less than a right angle to t e surface of theplate, I provide means whereby the direction or line of movement of suchprojectile shall be changed and the projectile caused to strike on theplate with its axis at an increased angle to the surface of the plateand at the same time break up and leave the projectile. To this end afrangible ring or collar 2 is placed on the projectile near its point,the said ring or collar being so constructed and arranged on theprojectile that its front or biting edge a will strike and bite into theplate ahead of the impact of any portion of the projectile if the lineof movement of the latter is not substantially at right angles to theplate. The biting of the forward edge of the ring or collar will retardthe under side of the projectile, so that its rear end will be turnedout in the direction of the arrow 1), thereby bringing the axis of theprojectile to such an angle that its point will engage the plate, andthereby insure the penetration of the latter by the projectile to theplate and, it is believed, aid and cause the projectile to pass throughthe plate. In order that the ring or collar may not operate tomaterially retard the penetration of the projectile, it is made easilyfrangible, so that it will be broken up and leave the projectile free sosoon as it has performed its tipping or turning function. T he ring orcollar is made, preferably, of an internal contour to fit snugly on theprojectile and can be placed at suchdistance from the point as not tointerfere with the use of the soft point or nose-piece now usuallyemployed with armor-piercing projectiles. If desired, accidentaldisplacement of the ring or collar may be prevented by a pin 3 driveninto a small hole in the projectile or by a set-screw 3, whichpreferably has its head countersunk, as shown.

I claim herein as my invention A'n armorpiercing projectile having apiercing-point in combination with a frangible ring or collar arrangedon the projectile in the rear of said point and adapted by engagementwith the armor or plate to change the direction of movement of theprojectile and aid in its penetration,substantially as set forth.

In testimony whereof I have hereunto set my hand.

JOHN WV. ANDERSON.
